Hello, To be more concrete, i use rrd files to store data extracted by the tool Flowscan. The tool calculates the bits/sec and packets/sec on a network. I store this result in rrd files (the tool calculate the average for 1 minutes).
For the moment, i use this parameters : step 60 DS:bytes:ABSOLUTE:300:0:U DS:pkts:ABSOLUTE:300:0:U DS:flows:ABSOLUTE:300:0:U and RRA:AVERAGE:0:1:4320 RRA:AVERAGE:0.8:5:2016 RRA:AVERAGE:0.94:15:2976 Flowscan tool returns only values different to zero. If there is no data, it means that there is no flow on the network (zero value). do i use correct parameters ? 2008/2/4, Fabien Wernli <[EMAIL PROTECTED]>: > > On Sun, Feb 03, 2008 at 06:48:06PM +0100, Gwenael Lahay wrote: > > I update my rrd file to put zero values because my rrd file stores 3 > > frequency of the same data. > > and only one of the 3 gets updated at any one time? > > > correctly the average value for 5 minutes and half and hour. > > For example, i have the following value for a 5 minutes interval : > > NaN 3 NaN NaN NaN NaN > > The program store a NaN data for this 5 minutes interval. > > so what is Nan: the measure (rrdtool fetch output) or your calculation > (rrdtool graph) or both? > If you manually calculate the average between frequencies, you may wanna > play with RPN IF expressions to check for nan values > > _______________________________________________ > rrd-users mailing list > rrd-users@lists.oetiker.ch > https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users >
